Ruby中简洁的方式来操纵这个字符串

Question

有时候我喜欢学习如何做“Ruby”的方式。我想知道 - 什么是采取一个字符串，如最简洁，易读的方式：

foo-bar

并操纵它来阅读：

Foo Bar

Answer 1

"foo-bar".split("-").map(&:capitalize).join(" ")

Answer 2

"foo-bar".gsub(/\b(\w)/){|m| m.capitalize}.sub '-', ' ' 

Answer 3

>> p "foo-bar".scan(/\w+/).map(&:capitalize).join(" ") 
"Foo Bar" 
=> "Foo Bar" 
>> p "foo---bar".scan(/\w+/).map(&:capitalize).join(" ") 
"Foo Bar" 
=> "Foo Bar" 
>> p "foo 123 bar".scan(/\w+/).map(&:capitalize).join(" ") 
"Foo 123 Bar" 
=> "Foo 123 Bar" 

Answer 4

string = "foo-bar" 
"foo-bar".split("-").map(&:capitalize).join(" ") # edited to because former answer was not optimal
